Y= -0.25x + 4.7 Y=4.9x - 1.64

Mathematics
1 answer:
Andreas93 [3]4 years ago
3 0

Answer:

The answer would be (1.23, 4.39)

Step-by-step explanation:

Because they are both equal to y, we can set the equations equal to each other and then solve.

4.9x - 1.64 = -0.25x + 4.7

5.15x - 1.64 = 4.7

5.15x = 6.34

x = 1.23

Now that we have the value for x, we can plug into either equation and find y.

y = -0.25x + 4.7

y = -0.25(1.23) + 4.7

y = -.31 + 4.7

y = 4.39

A line has a slope of -3/4 and has a y intercept of 3. What is the x intercept of the line
natima [27]

Answer:

The x-intercept is 4

Step-by-step explanation:

We are given;

The slope of a line as -3/4

y-intercept is 3

We are supposed to determine the x-intercept;

We need to know that;

The slope of a line is given by the ratio of the change in y to the change in x

The coordinates of y-intercept are (0, 3)

Taking the x-intercept as a, then the coordinates of x-intercept is (a, 0)

But;

slope = Δ in y ÷ Δ in x

Therefore;

\frac{0-3}{a-0}= \frac{-3}{4}

Solving for a

-3a = -12 \\    a =4

Therefore, the x-intercept is 4

Choose the polynomial written in standard form.
motikmotik

Answer: x4 + 4x3 + 10x2 is the correct option

Step-by-step explanation:

The standard form a a polynomial depends is written with respect to the highest power to which the variable or unknown of that polynomial is raised. The term which is raised to the highest power always begin the polynomial. This is followed by the other terms whose variables or unknowns has lower are raised to lower powers and it is in a descending order.

Looking at the polynomials given, the only one written in standard form is

x4 + 4x3 + 10x2

The powers of x are arranged in a descending order.

What is the missing step in the given proof? A. ∠PQC and ∠ACP are supplementary by the Linear Pair Theorem. B. For parallel line
ANTONII [103]

Answer:

<h2>D. For parallel lines cut by a transversal, corresponding angles are congruent, so ∠OCP ≅ ∠ABC.</h2>

Step-by-step explanation:

Since we need to show the connection of the proof from m∠OCP + m∠PCQ = 90° by the transitive property of equality to the definition of congruent angles, m∠OCP= m∠ABC,  letter D which states that For parallel lines cut by a transversal, corresponding angles are congruent, so ∠OCP ≅ ∠ABC is the only statements that fits to what we need to show.
